The National Highway Traffic Safety Administration (NHTSA) has issued the following recalls:
Kenworth is recalling model year 2010 T2000, T800, T660 and W900S trucks manufactured between July 1 and October 23, 2009. The fasteners attaching the steering gear to the front drive bracket may have received insufficient torque during the installation process, resulting in less than required clamp load. The insufficient clamp load may allow the fastener(s) to become loose and fall away from the vehicle resulting in road debris. If multiple fasteners were to become loose, the vehicle steering may wander, which could result in a crash. Dealers will inspect and re-torque the steering gear mounting bolts free of charge.
Certain model year 2010 Peterbilt 320 trucks equipped with Hendricskon HLR2 non-steering pusher axles fail to comply with requirements of Federal Motor Vehicle Safety Standard No. 121, “Air Brake Systems.” The trucks were not manufactured with the required number of air tanks for proper operation of the vehicle’s brake system.
Navistar is recalling certain model year 2009-2010 ProStar and LoneStar trucks equipped with roll stability control (RSC). The air line that supplies the traction solenoid valve of the RSC system may have been connected to an incorrect port on the air tank. This condition will affect air modulation to the trailer if RSC is activated during a roll-stability event. This condition does not affect the normal design function of the tractor and trailer service brakes when activated by the driver or the function of the tractor RSC system. Less than optimal RSC control of the trailer brakes during a roll-stability event may increase the risk of a crash.
Certain model year 2007-2009 Autocar WX and WXR LCOE vehicles may develop cracks in the top flange of the front frame rail extension. Over time, the crack may propagate across the extension bracket, potentially causing the extension bracket to deform under load. This may compromise the control of the vehicle, increasing the risk of a crash.
Certain model year 2008-2009 Autocar ACX vehicles may experience a fatigue failure of the steering gear mounting bracket. Over time, this failure may cause cracks that will result in undesirable movement of the steering gear mounted to that bracket. This may affect the control of the truck, increasing the risk of a crash.
Daimler Trucks is recalling certain model year 2010 Freightliner Cascadia trucks manufactured May 20, 2009, through January 29, 2010, and equipped with Sheppard HD94 steering gears. Restraining washer locking tabs may not have been seated into the pitman arm retainer notches during assembly. Incomplete installation of the pitman arm retaining mechanism may allow unthreading of the retainer. Disengagement of the pitman arm from the steering box may result in loss of steering and a crash could occur.
The axle beams on model year 2002 through 2004 Mack CL, CV, LE, MR, RB, RD and model year 2003 through 2004 DM trucks manufactured from Feb. 1, 2002, through Sept. 30, 2003, may have transverse shear lines on the bottom of the axle from the trimming process. These lines can promote initiation of cracks, which over time may lead to axle beam failure.
The adhesive used in the upper window in the bunk area to secure glass on certain model year 2010 to 2011 Volvo VNL trucks may de-bond. This could allow the glass to come loose and fall out increasing the risk of a crash.
Certain model year 2008 through 2010 Freightliner Cascadia’s may have lifeguard rolltek advanced occupant protection systems installed improperly. Reduced effectiveness of the system may increase the risk of injury.
There may be corrosion at the base of the optional jump start stud on certain model year 2008 through 2010 International trucks. This corrosion could cause an electrical short between the stud and battery box. An electrical short may cause a vehicle fire. A final remedy for this defect has not been determined, but the interim action involved removing the jump start stud and the connecting cable. n
